Rockbrook is an “overnight” summer camp, an example of what some call a “sleepaway” camp. This means that girls come and spend the night at camp for several days or weeks. Another term you might hear is “residential,” but no matter which term— overnight, sleepaway, or residential —joining a session at Rockbrook means you’ll sleep in a cabin at night. On the other hand, some camps have campers only during the day. These are called “day camps.” Rockbrook does not have a day camp.
How about this… “At Rockbrook, campers are residents who sleepaway from home overnight.”
